Ah, cool. Sounds like there's no excuse. My mistake.
I mistakenly assumed you'd need some kind of cryptographic key signing handshake via active electronics from within the keyfob to achieve secure comms with the host vehicle, and that such a requirement may have been some kind of implementation limiting factor, security-wise.
